電動車両
Document Type and Number:
Japanese Patent JP6831167
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric vehicle equipped with an air-conditioning device capable of effectively eliminating humidity by efficient operation of a heat pump and performing temperature control in comfortable condition even with increased percentage of inside air circulation (with no fogging).SOLUTION: Control is made for operation of communication direction of medium by path switching means 12, and opening state and throttling state of a first expansion valve 8 and second expansion valve 9, latent and apparent heat of fluid at a temperature control heat exchanger 5, humidity control heat exchanger 6, and a collecting/releasing heat exchanger 7 are separately controlled, circulation of outside air and inside air is controlled, for controlling temperature and humidity in a cabin 3, and power of compression means 11 is suppressed by increasing a percentage of inside air circulation, for temperature control in comfortable state (with no fogging).SELECTED DRAWING: Figure 1
